Output Specifications
Accuracy is given as ± (% of output + counts of least
significant digit) at 23 °C ± 5 °C, with relative humidity less
than 80% R.H., and warmed up for at least five minutes.
Constant voltage and constant current outputs
[1]
The maximum input voltage protection is 30 VDC.
[2]
Loading coefficient: 0.012 mV/mA for 1.5 V output.
[1]
The maximum input voltage protection is 30 VDC.
[2]
Loading coefficient: 1 μA/ V, the minimum output voltage is based on 20 mA into a 600 Ω load.
[3]
If the current loop has a 24 V power, a minimum output voltage of 24 V is achievable with a 20 mA current in a 1200 Ω load.
This is only applicable for the simulation mode for mA output, refer to “Simulation Mode for mA Output” on page 88 for more
information.
